Audeze LCD2 Classic Open Over-Ear Planar Magnetic Headphones Measurements

Measurements

Raw frequency response plots show the LCD2C is effected very little by changes in position on the head at frequencies below 1kHz, but some modest changes can be seen 1-3kHz.

Bass is ruler flat to 10Hz; a look at the 30Hz square wave and virtually non-existan bass distortion validate my experience that the LCD2C has fantastic bass response.

Midrange response is likewise flat to 600Hz and then starts a gradual and ever increasing rise to the 3.3kHz peak. This rise matches the Harman target well, but is overall a tad on the low side with only a +10dB peak at 3.3kHz. As can be seen in the compensated curve, this headphone does shelve down quite a bit between 1kHz and 4kHz and remains fairly flat at the lower level thereafter. Note there is a pretty good notch between 4-6kHz on both plots. I hear the headphone as being less rolled-off than measured, possibly due to the slightly grainy texture and/or the dynamic impact of these cans.

As mentioned previously, 30Hz square wave has excellent shape and remains well above zero over the entirety of the waveform indicating terrific linearity and extension in bass response.

300Hz square wave is a little course looking, possibly belying the grain heard in listening. Oddly, even though the frequency response plots show reduced levels in the treble, the 300Hz square wave waveform top is nominally flat. I would have expected it to rise givent the reduced treble response. This may point towards my listening observation that the treble doesn't seem as rolled-off as the FR plots would normally indicate.

Impulse response has a good leading transient, and has quite a bit of ringing initially, which is quite normal for a planar magnetic headphone. However, the noise continues, albeit at a low level, for quite some time, which may be further evidence of the grainy sound. This time domain response is better visualized with a cumulative spectral decay plot. I'll point you to Hands' post on SBAF in which he shows this measurement and makes comments regarding this 'hash.'

The THD+noise plot may be the lowest I've seen. Just astonishing. It does seem likely to me that this extraordinarily low level of distortion combined with the dynamic punch of these cans may be the defining character perceived in listening. The grain may get in the way a bit, but they are fundamentally a remarkably punchy and clean sounding headphone.

Impedance plot shows a fundamentally flat 72 Ohm impedance. There is a minor glitch at 7kHz that does show up as an 'ortho wall' on Hands' CSD plots and on the right channel in Marv's CSD and distortion plots.

Isolation plot is typical for an open headphone. With 110mVrms needed to achieve 90dB at the ear, these headphones will be driven to useable levels with a portable source.

Hello Tyll! I was wonder if this review indicates a change in your opinion about distortion?

You wrote: "The good news is that measurements made both by me and others show the LCD2C has extraordinarily low distortion. So while they can be punchy and a little lacking in treble smoothness, they never get hard sounding...even at higher volumes. It seems to me this is what ties these headphones together for a solid listening experience: super low distortion; superb dynamics; a treble, though a bit grainy, that doesn't offend; and deep, controlled bass response."

Does this indicate a difference in opinion on the relevance of distortion? I notice that such products as the Mr Speaker's headphones and especially the Sonoma E-stat measure quite poorly in terms of distortion, but don't remember a reference to that in those reviews. I had assumed you fell towards the belief of a fairly high threshold of audible distortion, meaning most distortion is not audible. Has that changed recently, and can you tell me if it did what changed your mind?

Thanks!

Distortion is always a very important parameter that defines audio fidelity; alongside frequency response and noise. Low distortion becomes even more important for EQ, since it confines the magnitude of applicable FR correction.

Sonarworks describe briefly the benefit of low THD [below 1%] in their 'Studio Headphone guide 2018', as well:

I’ve found the included cable to limit the capabilities of the 2C that’s quite obvious. It makes them sound distant and bass notes kind of sound plastic and lack oomph compared to any of my inexpensive after market cables.
Just that swap out alone took the 2C from sounding very good to most excellent. Try it.

Heretix_Aevum's picture

When you say 'inexpensive' aftermarket cables, what kind of price are we talking? Any particular models you would recommend?

You're not the first person I've seen to complain about the cable, though I am skeptical about claims of cable improvement in the vast majority of instances. I also trust that Tyll would've said something if it wasn't up to scratch, as he did with the Fidelio X1.

I like Cardas cable for their midrange. Their bulk 2x24 cable is relatively inexpensive and can be found on eBay when searching for Audeze headphones. I can’t hear any difference between their bulk line vs their higher end line and that’s what makes it a great value.

Audeze are made in China, and they ship them from Shanghai port

I don't really care about the omission of a case for a headphone I'll use exclusively at home... If I were lucky enough to get a chance to travel to a meet or trade show I'd just buy a suitable cable for less than $125.

If you were to press me, I'd say the low introductory price that ended before many had a chance to hear/review the LCD2C bugs me more than the lack of a case. Are you backing off the assertion that cans need to get the tonal balance right to even think of reaching the WoF btw? Or is the LCD2C just close enough?

Great review Tyll. Really wish you’d have compared it to the latest 2026 fazor version, because that is more immediate competition for many potential buyers. As a new LCD-2F user, I’m more interested in how similar (or different) the two headphones sound, not really the AFO or other brands I’m not in the least bit interested in. But it’s all personal preference, I get that. By the way please can we call them by their official name: LCD-2C. It’s not LCD2C (clue: look on the headphone).

gLer's picture

Oops, I meant 2016F :)

Impulse's picture

Disassembled photos show the grills say LCD-3 on the inside tho, so don't look TOO closely. :P

gLer's picture

Yeah that’s true, but still... Tyll’s is the second review I’ve seen that misspells the proper name.

In Australia, the "$125" case is $229 AUD, which is a fairly hefty markup. The headphones themselves are $899 AUD, which makes them a great deal here! Since I have used the case for my LCD-XC exactly zero times, I'd say the case is an unnecessary option.

I don't understand the fuss about the pre-order/intro price. It's normal for a pre-order/intro price to be lower than the regular price (otherwise, what would be the point of having it?)

I'm enjoying the LCD-2C right now, as they have finally arrived in AU :)

Pokemonn's picture

it really sounded very very good!
probablly I am going to click an order..

to those of us who use headphones only at home and have little storage space for such things. Get a nice case and what do you do with it? It's too nice to trash, and if you did what would that do to future resale value. In every case (pun intended) the case should be optional, especially if it means saving $100+.

GimmeCans's picture

$799 without a 'case 'feels' like the right deal IMHO because headphones don't get much less portable than this. My Beyer Amirons (Which you should review, Tyll) came with a hard zipper case that I will never use and lists for $85 (in case you lose it I guess) ; I wish they had lowered the price of those accordingly and left the case off. If I want high-end sound on the go I'll reach for my SE535 IEMs, but to each his/her own.

...about the case. A portable case, yes, not that useful. While the LCD-2 case is also ‘portable’ it’s actually more useful as a dust sealed storage case for keeping the headphones safe, clean, and accident free. It’s also great for storing cables and other accessories. I bought both my headphones (LCD-2F and Atticus) partly because of their storage cases, even though neither leave my listening room. I take special care of my expensive gear, and the extra protection and premium feel definitely adds to the overall value and experience. I don’t think 10-15% of the price of a headphone is too much to ask for a premium case. If were to buy the 2C one day I’d get a hard case for it as well, like Tyll suggests; heck I’d even do it for a “cheap” mid-fi.

I'm curious, do you put them away inside the case after every listening session? That seems like such a hassle, maybe I'm just lazy, I hang my primary/secondary headphones (an open/closed combo like you) on a stand and call it a day... Granted I made sure to find a stand with a nice wide base that wouldn't scratch, compress the padding, etc.

I'd actually take a nice stand over a case if I'm paying a premium for extras... But I imagine the weight/space of a nice stand would push things too far. There's a lot of crappy stands out there with arms that are too thin or rod-like, tho it's probably less of a concern for headphones like these with a suspension strap.

My current favorites are Silverstone's EBA01 and Jokitech's Air Cushion FWIW (not the Slim or Dual). If I were to put the headphones away on a secure box at home because I'm going on a long vacation or anything it'd have to be in something larger than them so I can throw in some desiccant (or Eva Dry boxes). Might seem paranoid but Puerto Rico's humidity can wreck havock with everything from rubber (shoe soles) to glass (camera lenses) to wood.

I enjoyed the LCD-2's but I found them to be dull and overpriced compared to cheap hi-fi sennheisers. They need to be less than $500 in order to compete with them.

As someone who goes to a lot of classical concerts, I have always held to the old Stereophile/TAS standard that the reference for any audio product should be how close it comes to reproducing the sound of live, unamplified music.

To me, the Oppo PM1 doesnt sound like music. I can hear/analyze the highs, the mids and the bass, but i cannot hear the musicality. I bought the PM1s after the enthusiastic reviews here, and that was when i realized that my preferences in sound are very different from that of InnerFidelity reviewers. This was reinforced when I listened to the various Focals - they are impressive products if you want to analyze the sound coming out of them, but not so good in re-creating the mood of an orchestra playing its heart out.

I had the privilege of getting fantastic seats to Temirkanov playing Shostakovich's #7 in St Petersburg, and it was an absolutely amazing performance. Listening to a lossless rip of his RCA recording of the same symphony on the LCD2 vs the Oppo PM1 is an absolutely different experience.

I say all this to put in perspective my somewhat brief statement: viz, if the LCD2 classics sound anything like the original LCD2 (which i still have), they will be possibly one of the nicest headphones in the sub-$1500 range for listening to music, *in my opinion*.

If you really want musical headphones then get Audio-Technica W3000ANV [used, as they are out of production]. Then you will know what musicality is. How can you listen to pieces of classical music with LCD2 ? They lack treble and treble extension. Because of this problem the tonality of instruments is all wrong. These headphones are for bass oriented Pop and ghetto music.

hackmartian's picture

Every interpretation or intent of a phrase like that I can think of is wrong, unless you're a huge BDP fan and going for a very specific piece of music that you feel the LCD2s are properly voiced for. Otherwise, take that crap elsewhere.

vkalia's picture

"Ghetto music"? Charming. And thank you for your efforts to teach me about musicality. After 20+ years of being interested in high quality sound reproduction and live concerts, I still prefer to go with what my ears tell me a violin or a piano should sound like, live.

I have owned a pair of AT headphones - some wooden jobbies: 3000 or 5000, forget the model number. Another example of cans where you listen to high/medium/lows, as opposed to the cohesive whole.

Why u no AKG K712 PRO?

The lack of any AKG reviews is conspicuous on this site, however the K712 especially seems to have a more full-range appreciation than the 701/2 series. I find the disregard a bit unfair by this point, and it does headphone buyers a disservice. They will look at it anyway, just not here, and it makes comparisons harder.

jmsdnhw's picture

the price is ridiculous if one buys the case which is included w the lcd2 wood version it is about the same . so one gets for an almost identical price cheaper construction materials and less technology. as i would rather have the lcd2 with out the fazor technology I'm conflicted that the company discharging me the same price for a headphone of inferior construction material and a design already 10 yrs old. this in itself should justify a substantially lower price especially considering one can purchase directly from audeze who therefore avoiding distribution and dealer mark up. but apparently audeze thinks little of their customers to offer them less product for the same priced do it buy duplicitously displaying a lower price but when one considers the cost of the missing and probably needed super case and the expense of the missing but by my unwanted fazor element are in effect just creating a way to sell less of an already old product for what will net them the same or probably more. this is very disappointing from a company most likely making a profit due to their high prices and large percentage of the market.
